Let me start off by saying that I am completely heterosexual, and have never had thoughts about another man before in my life. Having said that, I will tell this story of what happened at my office a few months earlier.
It was Monday morning, and my boss came over and told me I will have a new guy named Dan sitting with me to be trained for the rest of the week. I dreaded hearing this news, as I did not have the patience to deal with somebody new, let alone some guy. They could have at least sat a cute girl with me. Anyway, Dan came over an hour later, and I could not help but notice his striking good looks. He was 6'2'', about 190 lbs. He had dark hair and eyes, and appeared to be fairly well built. We exchanged pleasantries and he grabbed a seat right next to me.
Getting back to myself for a minute, I am 5'10'', 170 lbs, with dirty blonde hair. My cock is a healthy 7.5 inches long, and pretty thick. I had been having problems with my girlfriend, and things appeared to be over between us. I hadn't gotten laid in two months, so you can imagine how horny I was for some action. I was so horny that I would get hard ons during the day at work and I would have to sit at my desk until they went down.
As Dan sat down next to me that day, there was just something about him, and I could have sworn my cock twitched in my pants as I watched him. As I showed him the ropes over the next few days, I realized how hands on he was, often touching my shoulder, leaning over me to get files. Each time this happened, I would feel this electricity going through my body, my cock would begin to grow harder and longer down my leg, and it was beginning to really freak me out as a straight man. I don't know if Dan saw what he was doing to me, but if he did, he said nothing.
At 28 years old, Dan was two years older than me, and like me, he lived in an apartment nearby our office. He explained to me how he lived alone, and I noticed he never mentioned a girlfriend or wife. But anyway, I will fast forward my story to Friday, where we were permitted to wear jeans for the day. Dan strolled over to my desk in the morning and my eyes were immediately drawn to his crotch, where his tight jeans seemed to bulge prominently. As he sat down, my eyes remained focused on his crotch area, and I didn't even realize how long I was staring. But Dan did. I didn't see it but his face showed a slight grin as he watched me watch him.
We worked as usual, though we were now more friendly and joking by our fifth day of working together. As I explained a procedure to Dan, I felt uneasy as his bulge loomed right nearby, on display for anyone to see. I stole quick glances when I thought it was safe, but it began to take an effect on me. My own cock was erect, and I was doing everything I could to conceal it. Dan surely saw what was happening, and he tried to spare me the embarrassment by excusing himself to go to the bathroom. While he was gone I tried my best to think about non sexual things, and I wondered how I could be so turned on by a guy!
